Description

DESCRIPTION

BICYCLE ROLLER

OBJECT OF THE INVENTION

The object of the present invention, as the title of the invention establishes, is a roller for bicycles, understanding roller as a device where the user fits his bicycle (road or mountain) to pedal in a fixed place and normally indoors. . It is customary to use it to warm up before competitions or when weather conditions prevent the practice of cycling outdoors.

The present invention is characterized by the special design and configuration of each and every one of the parts that form part of the roller so that a robust, efficient and practical roller is achieved.

Therefore, the present invention falls within the field of bicycle rollers.

BACKGROUND OF THE INVENTION

Different types of bicycle rollers are known in the state of the art, specifically:

- Rollers with three rollers: it works with the two wheels of the bicycle and its main characteristic is the balance on the bicycle. Two rear rollers serve as support for the rear wheel of the bicycle (drive), and a simple transmission by means of an elastic cord makes the third roller rotate at the same speed, on which the front wheel of the bicycle rests. The main advantage of these rollers is that you do not have to modify the settings of the bicycle at all, but simply rests on the roller with three rollers, without any type of anchor. These rollers do not allow a stronger resistance to be applied. Beyond the moment of inertia accumulated in the three rollers, however, they allow the cyclist to ride empty and warm up their muscles and joints before a sporting competition.

- Roller rollers with variable resistance (Smart): the bicycle is attached at the rear wheel to the roller structure, and an electronically controlled variable resistance system regulates the power that the cyclist must develop to maintain the pedaling cadence. The traction of the bicycle is transmitted to the roller by the friction of the rear wheel cover on the roller roller. There are various systems for the application of variable resistance, the most common being the magnetic braking system. Said magnetic brake can be based on variable force electromagnets, or on fixed magnets, generally neodymium, which are located in variable positions depending on the braking force that is desired to obtain.

- Direct transmission rollers with variable resistance (Smart): roller that integrates an axle and a standard cycling core, where you can install the bicycle sprocket and anchor it to the roller by its fork, after disassembling the rear wheel of the bicycle. The traction of the bicycle is transmitted directly to the roller through the chain, the derailleur and the standard sprocket of the bicycle itself, without friction losses and without degrading the rear wheel cover, as occurs with rollers. roller. The variable braking systems are similar to those of the Smart rollers, the main advantage being the absence of friction and degradation of the cover.

For several years, the use of interactive rollers has become fashionable, a way of playing sports virtually through simulation platforms. These software platforms are available for PC, tablet or smartphone, and are generally connected to the Smart trainers via Bluetooth or ANT+ wireless connections, simulating the variable slopes of virtual routes, measuring the performance of each connected cyclist, and ultimately making virtual competition in indoor cycling as an e-sport possible.

It is also possible to find direct drive rollers on the market whose resistance system is not electronically controlled, but depends exclusively on the speed of rotation, through the use of non-Newtonian fluids. These rollers have a system for anchoring to the bicycle identical to those described above, however they do not allow simulation and virtual competition through software platforms.

Currently, the existing trainers on the market have aspects that can be improved, for example, in some of the trainers it is not possible to change from a road bike to a mountain bike and vice versa; in other cases, the pulley does not have a reinforced design that extends its useful life; In other cases, the casing does not have a recess that allows the derailleur hanger to enter the roller, to allow the cyclist to insert the largest sprocket in his sprocket; in other cases they do not have cable data connections to be able to extract and display all the operating data on a computer even in environments with wireless interference.

Therefore, the object of the present invention is to overcome the aforementioned drawbacks, developing a roller that simultaneously has all the possible improvements indicated, according to the characteristics described below and included in its essentiality in the first claim.

DESCRIPTION OF THE INVENTION

The object of the present invention is contained in its essentials in the independent claim and the different embodiments are contained in the dependent claims.

The object of the present invention is a bicycle roller that has a base or support to which removable legs are fixed. about bliss base there is a lower casing on which the main pulley (drive) of the roller is arranged.

The casing has a recess that allows the derailleur hanger to enter into the roller, to allow the cyclist to insert the largest sprocket of his sprocket, having implemented a step to allow said movement of the bicycle derailleur.

The trainer has a direct USB socket to be able to use the trainer directly connected to the PC via cable, and thus avoid wireless connection problems that sometimes occur due to Bluetooth or ANT+. The user does not have to install any type of driver on his PC, it is "plug & play". This direct USB connection does not currently exist in any commercial trainer, and it is compatible with all simulation software platforms.

Said "USB" connection socket is arranged on the lower casing in combination with the power socket and with a backlit button. It is part of the roller itself, without the need for any additional accessory, so that this unique functionality on the market does not represent no extra cost for the end user.

The legs have two possible configurations: normal for road bikes and below for mountain bikes. With this ingenious solution, the user is prevented from having to raise the front wheel to a plastic chock, which is the solution that manufacturers have proposed so far. Mountain bikes are less frequent when it comes to rollers, and they have the difficulty that their wheels are generally larger, with the 29" measurement being common for a few years, while road bikes are usually 27.5" as much.

Unless otherwise indicated, all technical and scientific elements used herein have the meaning ordinarily understood by one of ordinary skill in the art to which this invention pertains. In Methods and materials similar or equivalent to those described herein may be used in the practice of the present invention.

Throughout the description and claims, the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and characteristics of the invention will emerge in part of the description and part of the practice of the invention.
